SHELL-MARKING MACHINE.

Specification of Letters Patent.

Patented Jan. 15i1918.

Application filed October 29, 1915. Serial No. 58,733.

To all whom it may concern -,Be it known that I, Joirn Moornny Brown, ofthe city of Hamilton, 111 the countypf Wentworth, Province of Ontario,

Dominlon of Canada, have invented certain new. and umful Improvements inbhell- Marking lvlachines, of which the following is the specification.

My invention relates to improvements 1n shell marking machines, and theob]ect of the invention is to devise a machinejor marking the base ofshells with the required data, in which the pressure is impartedgradually to each individual type, thereby eliminating all crushingstrain tending to deform the type, and in which the depth of theimpression may be regulated; and it consists essentially of a markingchuck secured to the base of the shell and carrying individual typeslugs, a saddle holder in which the body of the shell rest-s, a pressuremember bearing against the nose of the shell, and a revolving pressurechuck designed to successively bear against each invidual type piececarried in the marking chuck, as hereinafter more particularly explainedby the following specification. v

Figure 1 is a side elevation of my machine shown the marking chuck,pressure memher an revolving pressure member in section;

Fig. 2 is e cross-sectional view on line ti 1, Fig. 1..

Fig. is an enlarged perspective detail of the in:

king chuck. n 4; a detail of one of the type pieces in side"e"l'cvation.

1 indicates the bed of the machine. 2 1ndicates the base of the saddlemember which is slidably secured in position by screws 2 on the slideway1 forming part of the base of the machine. 3 indicates the saddle whichextends upwardly from the base 2 and 1s provided with ascmi-octagonalrecess Bfiextending longitudinally of the machme. 3'indicates a, series of grub screws whichiare threaded into each an face3 3?, and 3";of' the recess 3" and on which the body of the shell 4is'designed to rest when in ositi'on. 5 indicates a cap member alsoprovi ed with s: semi-octagonal recess 5* opposing the re cess3" andalso provided with grub screws fi' bcilrin against the upper peripheralportfltm of the shell when the cap untho plates 10 and 11 are connecteing a link 6* pivoted to the projecting portion of the saddle piece 3 atits lower end and extending upwardly through the notch 5 formed in theoutwardly extending flange 5 of the cap 5. 6 indicates a lever pivotedat its inner end to the upper end of the link 6 and provided with adepending eccentric portion (Sibearing against the flange portion 5" ofthe cap 5.

Although I have shown this form of clamping means it will, of course, beunderstood that various other means might be employed for accomplishingthe same purpose.

The type'slugs 9- are set in the annularspace 7 in annular series with the notch 9 facing outwardly.

10 and 11 indicate semi-circular plates which are placed against thebase of the annular member 7 so that its inner peripheral portionextends into the notches 9 of the type 9. It will be seen by referringparticularly to Fig, 1 that the plates 10 and 11 are thin plat-en so a:to permit of the longitudinal' movement of the type 9 within the annularspace 7 12 indicates intervening blocks which. are inserted in theannular space 7 between each set of type forming a. word or completenumber. 12 indicate securing screws extending through the"'annularmember 7 through the blocks 12 into the central solid portion 8 (if themarking chuck. 11 indicate screws b which the to the base of the member7". p i

28 indicate rollers journalecl, upon. the pin 27 at diametricallyopposite points of the revolving pressure niei'uber Q3 and in such aposition as to bear against the outer end of the type slugs exteruling'lrorn the 25 marking chuck 7i 2 indicates av ball-blur ing memberlocated bet ween the rota ry pressure nien'iber and the lard 2:2.

Having described the prineipul parts in volved in my invention I will.briefly describe the operation ot'ithe same.

The marking chuck is first sccurwil to the base of the shell by meansof. tiib seescrcw 7". The shell. is then placed in the saddle 3 upon theinwardly projecting grub screw-vs 3 and with the nose of the shelleidiesuline into the recess 19 of the blocl; l The grub screws 3' areadjusted so as to insure the proper horizontal alinemcntoi the shellwhen in position The cup 5 is then closed 40 down upon the top of theshell and clamped in position by means of the le securing the shell in astat onary The slnrft 2O then mutat d so rollers 28 are carried N cely,in. or #fioutw-rrdly projecting nds the ilrgu; The lEEllRFl-Wli, l 16 isH turn ll .1 s l pressuiu n a line parallel with tin longitudinal axisoi the shell. tl er lri ca1'r ing the shell, saddle member and ndard 18longitudina ly toward the rotary ssure member their y pressure betweenthe rollers and the outer end of th them forward against the base of theshell to form the in'ipressiou.

It will be seen that the type 9 are arranged in annular series and that.llH.-=F( ii1l.(., the -rollers 28 travel successively over the type.and, therefore, form the impre ion not by one single pressure but by aseries of coin-- paratively light pressures repeated as the rollersQSJTJEIkEl their revolutions over the type. i

I: will be readily understood that if an impression is made by oneoperation or by ype -l so as to gradually force great pressure madeinstantaneously that there would be a lcmleucy to crush the type andthereby (lestrcy its usefulness. By my machine the pressure. is exertedgradually and successively on each of the type members and,tl'nzre'lore, the impression is gradually made and any danger ofcrushing the type eliminated,

What I claim as my invention is:

l. in a shell marking machine, the combination with the shell holder,and a mark in ehuclc adapted In be secured to the base of the shell andto carry a series of suitable type slugs, ol. means for graduallyexerting pres-mire sir c rely on each type piece to :l'orni an iin ision on the base oi" the shell.
